I work in visual effects. Large companies (Disney, DreamWorks, ILM, Weta) are all Linux based, while small shops are Windows or Mac. So much of the software is cross platform in order to be relevant (usually Linux first). Maya, Nuke, Houdini, rv, and a bunch more. All of the smaller tools and utilities in open source projects are either Qt or PyQt. Maya, Nuke, and Houdini all had their own in-house toolkits, but migrated to Qt. They all have fairly custom UI requirements, require high performance, and need high end things like accurate color and GPU acceleration. It's not the same type of app as Spotify or Slack, but is comparable to VSCode.
